TALURUS.—METAXYONYCHA. 217 
TALURUS. (To precede the genus Metaryonycha, p. 128.) 
Talurus, Lefévre, Ann. Soc. Ent. Fr. 1889, p. 337. 
This genus has been lately established by Lefévre on two species placed by me in 
Rhabdophorus* ; these species differ, however, from Rhabdophorus in the very transverse 
thorax, the sides of which are rounded and entire, the filiform antennee, and the longer 
first joint of the posterior tarsi. Lefevre erroneously describes the eyes as entire; they 
are distinctly emarginate on their inner edge. 
1. Talurus salvini. 
Rhabdophorus salvini, Jac. huj. op. p. 148, t. 9. fig. 2. 
Talurus salvini, Lefévre, Ann. Soc. Ent. Fr. 1889, p. 337. 
Var. a. The head and the anterior margin of the thorax metallic green, the disc of the latter fulvous. 
Var. b. Below piceous, above dark purplish. 
To the localities given, add :—Muxico, Cerro de Plumas (L/6ge). 
Of the varieties I have received some Guatemalan specimens from the Stuttgart 
Museum; they do not differ much from the type, except in colour and in the more 
closely rugose interstices at the sides of the elytra. 
9. Talurus rugosus. 
Rhabdophorus rugosus, Jac. huj. op. p. 150, t. 7. fig. 8.

METAXYONYCHA (p. 128). 
Metaxyonycha chlorospilota (p. 129). 
To the Mexican localities given, add:—Atoyac in Vera Cruz (H. H. Smith), El 
Mirador (Flohr). 
2 (a). Metaxyonycha hirsuta. (Tab. XL. fig. 22, ¢.) 
Testaceous; thorax closely punctured, the lateral margins obsoletely bidentate; elytra strongly and closely 
punctured in rows, sparsely pubescent, strongly costate at the apex, a subquadrate spot at the base and a 
transversely shaped one below the middle metallic green. 
Length 33-43 lines. 
Head rather closely and strongly punctured at the sides, deeply triangularly depressed between the eyes, the 
apices of the mandibles black ; antenne long and slender, entirely testaceous ; thorax about one half 
broader than long, closely but irregularly and not very strongly punctured, the lateral margins obsolétely 
bi- or tridentate or merely sinuate, the anterior angles produced ; elytra not very deeply punctured, more 
sparsely so near the suture than at the sides, the interstices strongly costate near the apex, and sparingly 
clothed with stiff fulvous hairs, the shoulders with a subquadrate metallic green spot not extending to 
either margin, another spot of the same size, but of more transverse shape, placed below the middle; the 
first joint of the anterior tarsi widened, and the intermediate tibie strongly curved at the apex, in the 
male; the female with three or four short cost at the base of the elytra within the metallic green spot. 
Hab. Panama, Bugaba (Champion).
